domain of (2(x+2))/(x^2)

domain

\frac{2 ( x + 2 )}{x ^{2}}

x < 0 or x > 0

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

p er i o d i c i t y f (x) = - sin (4 x)

d o main - x^{2} + 16 x - 94

d o main f (x) = [2 x]

in t erce pt s f (x) = \frac{3}{4} x

m o n o t o n e f (x) = 3 x 2 x^{2} + 4

What is the domain of (2(x+2))/(x^2) ?
The domain of (2(x+2))/(x^2) is x<0\lor x>0
